The retailer reported an adjusted quarterly profit of $2.47 a share. That was significantly higher than the projected $2.16 a share, from a survey of analysts by Thomson Reuters.

Best Buy currently has 1,105 big-box stores in the U.S., not counting the pending closures, according to company spokeswoman Kelly Groehler. In China, there are 185 stores under the company's Five Star brand, she said.

The company plans to open 100 "mobile small format stand-alone stores" in the U.S. in fiscal year 2013. It also said 14 of the new stores in China will be "mobile store-within-a-store concepts."

Groehler described the "stand-alone" stores as small stores located in strip malls and similar retail locations. She described the "store-within-a-store" as a small Best Buy store located within a larger Best Buy store.
